Belden Inc. TUSDK072RI2N OS2 72-fiber Distribution Cable

Product Description

The BELDEN INC. TUSDK072RI2N is a tight-buffered distribution-style OS2 single-mode fiber optic cable designed for high-density indoor backbone and riser applications. With 72 fibers, this cable supports large-scale structured cabling installations where high fiber counts and low signal loss over long distances are required. OS2 single-mode construction provides a 9-micron core optimized for long-haul transmission, making it suitable for enterprise, data center, and campus backbone runs. Licensed low-voltage contractors and structured cabling technicians are the typical installers for this product.

This cable is suited for indoor distribution and riser environments in commercial and enterprise settings. The tight-buffered construction simplifies termination directly to connectors without the need for fan-out kits, making it a practical choice for high-fiber-count backbone runs between telecom rooms, equipment rooms, and main distribution frames. Its OS2 rating supports single-mode transceivers operating at 1310 nm and 1550 nm wavelengths across extended link distances.

Key Features

• 72-fiber count supports high-density backbone installations
• OS2 single-mode construction for low-loss long-distance signal transmission
• Tight-buffered design allows direct termination without fan-out kits
• Distribution-style cable suitable for indoor riser and backbone runs
• OFCR riser rating meets applicable fire safety requirements for riser pathways

Compatibility

Designed as an OEM-style distribution fiber optic cable for use with standard single-mode OS2 fiber optic connectors and termination hardware in indoor riser-rated structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or structured cabling contractor familiar with TIA-568 and NFPA 70 (NEC) Article 770 requirements for optical fiber riser cables. De-energize all active equipment connected to the fiber path before splicing or terminating. Observe the cable minimum bend radius at all times during pulling and routing to avoid fiber stress or damage. Do not exceed the rated pulling tension specified for the cable during installation.
